DOOR-HANGER.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed October 24, 1916. Serial No. 127,481.

To all whom it may concern:

Be it known that 1, ANDREW F. LARSON,

a citizen of the United States, residing at Portland, in the county of Multnomah, State of Oregon, have invented new and useful Improvements in Door-Hangers, of which the following is a specification.

My invention relates to a linking support for sliding doors and has as its principal object the provision of a cheap and simple, linkage arrangement whereby a door may be supported at two points only, but'will open and close in substantially a horizontal direction.

Further objects of my invention will be obvious to those skilled in the art from an examination of the following specification and claims in connection with the accompanying drawings.

In the drawings Figure 1 is an elevational view of my improved supporting linkage as applied to a door, the lower portion of the door being broken away and the door being in the closed position.

Fig. 2 is a view similar to Fig. 1, except that the door is in the half opened position.

Fig. 3 is a view similar to Figs. 1 and 2, except that the door is in the fully opened position.

Fig. 4 is a sectional view taken through the right hand vertical links shown in Fig 2.

Throughout the separate views the same part is designated by the same reference character.

Referring more particularly to the drawings, l designates a door which is pivotally supported at the points 2 and 3 only, being connected at said points to the long links 4 and 5 respectively. The links 4 and 5 extend upwardly from the door in the position of the parts as shown in the drawings and are pivotally connected at the points 6 and 7 with the relatively short links 8 and 9, respectively. Somewhat above the level of the points 2 and 3 I attach to the wall 10 a strip or plate 11 to which the links 8 and 9 are pivoted at the points 12 and 13, respectively.

It will be seen that the links 4 and 5 not only extend below the lower ends of the links 8 and 9, but also extend upwardly somewhat beyond the upper ends of the links 8 and 9, the links 4 and 5 having pivot 55 points 14 and 15, respectively, near their upper ends. Moreover, the links 8 and 9 are provided with the pivot points 16 and 17, respectively, not far from their upper ends, but below the points 6 and 7. Connecting the points 14 with the point 17 and pivoted at each of said points is a link 18, and connecting the point 16 with the point 15 is a link 19, the links 18 and 19 being pivoted together at their centers as shown at 20.

From the foregoing,'it will be apparent that the links 4 and 5, and also the links 8 and 9, remain parallel to each other as the door moves from side to side, and that the door is effectively supported and guided in a horizontal pass without the necessity of a guide or other connecting points on the Wall or on the door, than the points 2, 3, 12 and 13.

Having thus described my invention, I claim 1. A supporting linkage for a door or the like, comprising in combination a pair of relatively long links, and a pair of relatively short links; the lower ends of said long links being connected by pivot points to the door; and the lower ends of said short links being connected by pivot-points to a fixed support, theupper end of the short links being connected by pivots to points on the long links, which points are.

situated below the upper end of said long links, and means interconnecting said short links and said long links for preserving a predetermined relation therebetween throughout the movement of said door.

2. A supporting linkage for doors and the like comprising in combination, a pair of relatively short parallel links pivoted to a fixed support, a pair of long links pivoted to the door, said short links being pivoted to said long links, and a lazy tong for maintaining said short and long links in parallel relation.

' 3. A supporting linkage for doors and the like comprising in combination, a pair of relatively short parallel links pivoted to a fixed support, a pair of long links pivoted to the door, said short links being pivoted to said long links, said long links extending beyond said pivotal connection with said short links, a link connecting the end of one of said long links with one of said short links, and a link connecting the second one of said long links with the second one of said short links.

4. A supporting linkage for doors and the like comprising in combination, a pair of links, and a link connecting the second one relatively shortparallel links pivoted to a of said long links With the second one of]? fixed support, a pair of long links pivoted said short links, said last tWo mentioned to the door, said short links being pivoted links being pivoted together at their centers.

5 to said long links, said long links extending In testimony whereof I hereunto afiiX my beyond said pivotal connection With said signature this twenty-third day of October, short links, a link connecting the end of 3.916. one of said long links with one of said short ANDREW F. LARSON.
